Thoracentesis

Thoracentesis is a procedure that uses ultrasound to locate a pocket of free fluid within the chest cavity. This assists the radiologist in placing a temporary catheter to drain the fluid.

Procedure

You will lie on an exam table with your back exposed.

A non-greasy gel will be applied to your skin during the exam.

The sonographer will use a hand-held transducer (probe) against your back to obtain images of the fluid in your chest.

The sonographer then shows the radiologist the largest pocket of fluid.

The radiologist numbs the area with Lidocaine to aid in any discomfort the procedure causes.

The radiologist then sterilizes the area and places a temporary catheter within the chest.
